Application filed December 10, 1912. Serial No. 785,888.

To all whom it may concern:

Be it known that WB ,'CLIN'1ON L. Wonrn and BERT W. WOLFE, citizens of the United States, residin at Brooklyn, in the county of Kings and tate of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in looks and has for its object to provide means a door partially broken away, showing in elevation our improved lock, Fig. 2 is an enlarged detail sectional view of a lock case and operating means, Fig. 3 is a section on line AA of Fig. 2, Fig. 4 is a detail sectional view of a lock releasing means, Fig. 5 is a detail end elevation of a weight operated lever member, Fig. 6 is a perspective view of a portion of a door having my locking means thereon, Fig. 7 is a detail top plan view ofa lock-member, Fig. 8"is an elevational view thereof, Fig. 9 is a section on line FF] of Fig. 1, Fig. 10 is a section on line FF of Fig. 1, Fig. 11 isa view similar to Fig. 1 showing a modified form of lock, and Fig. 12 is an enlarged detail view of a lock operating device.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings in which- 1 indicates a door having a centrally disposed lock casing 2, in it vertical edge 3. Recesses 4 and 5 are also formed in the door near its horizontal edges 6 and 7 to receive the lock members 8 and 9 and the mechanism by which they may be operated and which will presently be described.

In the casing 2 is a horizontally slidable lock bar 10 formed with a rack 11 on its edge 12 and with recesses 13 and 14 in its op-.

therein by a spring 17, said tongue being adapted to limit the movement of said lock bar 10 when seated in the recess 14. A key 40 is; adapted to operate the member 18 which has a wing 19, one end of which fits in the groove 20 in said tongue 16 is adapted to ralse the tongue against the tension of the spring 17 whereby the member 16 will travel. a greater distance and project considerably farther out of said casing and farther into a recess to be provided therefor in a door casing (not shown) and whereby thesaid tongue 16 may enter the recess 15, which is of a width just sufiicient to receive said tongue and hold said lock bar 10 fixed against any movement. A gear wheel 21 having an opening 22 to receive the shank (not shown). of the knob 23 whereby the teeth 24 of said wheel engaging the said rack may operate said-lock bar. Secured to a member 10 on said bar 10 and slidable on the channel 10 are a pair of chains 25 and 26, the former extending upwardly and over the pulley 27 and connecting with the rod 28 which is secured to the lock bar 29. Also secured to the rod 28 is a chain 30 operating over the pulley 31 and suspending a weight 32 which is adapted to normally hold the end 33 of said bar 8 normally projected out of its casing 34.

The chain'26 extends downwardly and operates over the pulleys 35, 36 and 37 and thence connects with the reduced end 38 of the lock bar 9. Pivotally mounted in the recess 5 is a lever 39 having an angular bifurcated end 41 which is adapted to straddle the-reduced end 38 and engage the shoulder 42 and the pins 43 on said-end 38. A weight 44 is provided on the end 45 of the member 39 whereby the member 39 will be lowered by gravity and consequently cause the bifurcated end 41 to normally force outwardly the lock bar 9. However when said bar is drawn in by the operation of the bar 10 acting on the chain 26, the shoulder 43 will shove against said lever end 43 causing the weighted end 45 thereof to be raised as shown in dotted lines 46 in Fig. 1.

The operation of the lock is extremely simple as any movement of the lock bar 10, through the medium of the chains 25 and 26 and the weights 32 and 45 imports or permits of an equal movement of the bars 8 and 9 which cannot be operated independently of said bar 10.

In Figs. 11 and 12 are shown a modified form of the invention in which the lock bars 47, 48 and 49 connected by chains 50 and 51 and their working parts, are similar in construction to those shown in the other figures except that the bars 47 and 48 are pressed normally outwardly of the casings 52 and 53 by spring 54 and 55 instead of by meanstof other cases the preferred form is the most desirable as its operating parts would be .less apt to be affected by intense heat in case of fire.

When the lock bars are projected to the fullest extent (not shown in the drawings) they will be held in a fixed extended position by means of the tongue 16 in the recess I 15 and the door can only be operated by op eration of the key 40, as the lock bars will extend so far into sockets provided for them in the door casing that it would be a matter of impossibility to jimmy the door open.

' However when the tongue is seated in the elongated recess 14 all of the bars may be freely operated by means of the knob 23.

Having now described our invention that which we claim to be new and desire to procure by Letters Patent is: v
